CD4099BPW Equivalent & Substitute Parts

Part Overview

The CD4099BPW is an 8-bit addressable latch IC manufactured by Texas Instruments, designed for digital logic applications requiring addressable storage and latching functionality. This component operates across a wide supply voltage range of 3V to 18V and features standard output characteristics suitable for general-purpose logic circuits.

The CD4099BPW is classified as obsolete, which necessitates identification of active equivalent parts for new designs and ongoing production requirements. The CD4099BPWR serves as the direct manufacturer-recommended substitute, offering identical electrical and mechanical specifications while maintaining active product status.

Substitute Part Grouping Explanation

Substitution of the CD4099BPW is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Logic type: D-Type, Addressable configuration
• Circuit configuration: 1:8 addressing scheme
• Supply voltage range: 3V ~ 18V
• Output characteristics: Standard output type with 6.8mA drive capability
• Propagation delay: 50ns maximum
• Operating temperature range: -55°C ~ 125°C

Mechanical Equivalence Criteria:

• Package type: 16-TSSOP form factor
• Physical dimensions: 0.173" width, 4.40mm width specification
• Mounting technology: Surface mount

Compliance Equivalence Criteria:

• RoHS3 compliance status
• REACH unaffected classification
• Moisture sensitivity level MSL-1

The CD4099BPWR maintains complete equivalence across all specified parameters while differing only in packaging format (Tape & Reel versus individual packaging) and product status (Active versus Obsolete).
